"This information series explains how the human body functions. All books in the series include photographs, diagrams, and explanations that aren’t always as clear as might be hoped, but are still useful. The Spanish translation is accurate. The vocabulary is third grade level, but the readability level is higher in translation. This series will fill a void in my bilingual collection. –Kathryn Davis Arlington Independent School District 4/21/2010" - Arlington Independent School District
